Talkswitch 48-CA/CVA, 24-CA manual Support, Callers complain the sound is distorted or choppy

Problems that may occur with VoIP

I hear a re-order tone when I try to dial a VoIP location.

•Confirm the number dialed is actually part of the VoIP group (i.e. registered with the same proxy/registrar server as your TalkSwitch CVA, IP gateway or IP phone is registered with.

•Check that TalkSwitch has all proper settings in the IP configuration and VoIP configuration pages.

•Verify that the number you are dialing is registered with your TS proxy registrar. Go to System Information -> VoIP Configuration and click the View Registrar Entries button.

•Contact TalkSwitch for help at 888.332.9322.

Callers complain the sound is distorted or choppy.

•Your broadband connection may not have enough upstream bandwidth to support many simultaneous VoIP calls. Under Options -> Audio Controls, you may need to disable the G.711 and G.726 codecs and only use G.729.

•You may have too much data traffic on your Internet connection at the same time you are trying to make voice calls. We suggest that you use a router that supports QoS (Quality of Service) for VoIP.

When I call someone or they call me, voice is only heard in one direction.

•The cause of this problem is usually a result of a router being misconfigured with respect to port mappings. Ensure all required VoIP ports are mapped to your TalkSwitch unit. Also, ensure you use a static private IP address when connected to your router as this can also affect port mappings from the firewall/router.

•Use a router that supports the UPnP.
